摘　　要：为了了解鄂尔多斯沙地鼠类群落组成年度变化趋势,2008年到2012年采用夹日法对鄂尔多斯沙地鼠类群落组成及其数量进行了调查。调查结果显示,鄂尔多斯沙地鼠类群落由七种鼠组成,鼠类群落在5年间不断地发生演替。长爪沙鼠、子午沙鼠的年度变化趋势均与鼠类群落的年度变化趋势一致。多样性指数和丰富度指数的年度变化较为一致,物种多样性与丰富度和均匀度都有极显著的正相关关系。To understand the annual change trend of composition of rodent community in Erdos sand- land, composition and number dynamics of rodent community were investigated by the day trapping meth- od in Erdos sandland from 2008 to 2012. The results showed that rodent community was composed of sev- en species in Erdos sandland. The succession of rodent community constantly oecured in 5 years. Annual change trend of Meriones unguiculatus and Meriones meridianus both were the same as that of rodent com- munity. Annual change of diversity index was the same as that of richness index. The species diversity showed significantly positive correlation with the richness and the evenness.
